1250mm Mitsubishi / Hitachi 24 tons/hr Continuous Galvanizing
Line w/4-Hi Skin Pass Mill & all Line Components, Re:25781

25781

This is a fully equipped Continuous Galvanizing Line initially built new in 1980 and then in 2006 $20,000,000. USD was spent to extensively Rebuild and Upgrade the Line including replacing the 4-Hi Continuous Skin Pass Mill with a brand new Automated System as well as replacing most Line Items with brand new ones.

The main equipment list for the Line is a Shear Welder, the 4-Hi Continuous Skin Pass Mill, a Tension Leveler, Recoiler, Melting Furnace and one additional Furnace. Extensive information on the capability of the Line is listed below.
